If direct pressure with a sterile dressing fails to immediately stop severe bleeding from an extremity, you should apply: a. additional sterile dressings. b. a splint and elevate the extremity. c. a tourniquet proximal to the injury. d. digital pressure to a proximal artery.

C. a tourniquet proximal to the injury

Explanation:

Tourniquets are resources used when it is necessary to control bleeding from an injury where the dressing is not being sufficient. The tourniquet should be used as a last resort, ie when other types of bandages fail to stop a bleed. The tourniquet should not be placed in a joint because it would cause discomfort and movement problems in the patient. Ideally, the tourniquet should be placed close to the lesion at a distance of 5 centimeters.
